SACRAMENTO, Calif. (AP) – Lawmakers have approved legislation that would allow government regulators to monitor oil refinery shutdowns in response to a fire at Chevron’s Richmond refinery in 2012. It also would allow oil companies to designate the information as a “trade secret.”

SB1300 by Democratic Sen. Loni Hancock of Berkeley would protect information submitted to state officials from disclosure under the California Public Records Act.

The Assembly and Senate approved the bill late Friday, sending it to the governor.
